DNA replicates conservatively Semiconservatively liberally b
Solution
5. b) semiconservatively
The DNA is doube stranded with two strans in antipolar nature. During replication the two strands sepearate. A new strand is added to each one of them and thus we get two new double stranded DNA strands with one old strand and one new strand. Hence it is called Semi-conservative.
6. c) Derived from plasmid with an origin of replication.
The Bacterial artificial chromosome is derived from fully functional F plasmid. It is used to clone large DNA inserts and express inside E. coli. It has its own origin of replication and genes for homologous recombination. This Ori, helps it to replicate on its own inside the bacterial cell and maintain itself. However unlike actual chromosome it does not contain centromers or telomeres. Hence answer is option C.
7. DNA --> RNA --> Protein
It is the central dogma of Biology, in which the DNA acts as genetic material passes on its information to RNA (mRNA-messenger RNA) by a process called as Transcription. The mRNA is later Translated with the help of ribosomes into proteins. Athough there is another transition exists in which RNA is converted back to DNA, which is called reverse transcription ( Not mentioned in the question ).
8. d) The genotype is the genetic compostion of an organism, whereas the phenotype is its physical appearance.
The genotype is the genetic content, what genes the organism possesses. These genes gets transcribed and translated into proteins, which make up the appearance of the organism, in other words Phenotype. Phenotype depends largely on the genotype and genotype is hereditory.
